Murcielago has submitted us his new MP Mission for ArmA 2 called "CheckMate".

CheckMate missions are a new type of mission to show my new Arma creation, SWAP system.

SWAP system allows players to use the switch team member feature IN MULTIPLAYER MISSIONS! Basically this system allows you to swap from one unit to the other one but in addition I added some things...

When you use the SWAP system to change from unit A to B, unit A will carry on looking at the same direction and it will keep the same stance when you will take control of unit B.

SWAP system will keep the same looking direction for units inside turrets too and, aircrafts will keep the same altitude. For example you will be able to easily have a full control of an Apache helicopter. You will need only to swap to the pilot and move the helicopter to the desired location. Once you meet the enemy swap to the gunner and have fun!

Swap system is an universal solution as it works with infantry and vehicles in addition it adds a new huge number of possibilities to the game because with SWAP system you will be able to do things that you could not do before, for example, you can move your SWAP units as a SWAT team or, you can place AI units wherever you want (Taking cover behind a vehicle, looking through a window, inside a house facing the door...)

To complete the SWAP system I created the ChessMove system. This new system makes easy to move any unit/vehicle of your side. ChessMove system is a simple visual help that will move from individual soldiers to vehicles with two clicks on the map!

So I use these features a mission system where both players have exactly the same conditions and they need to fight to conquest an specific location. It looks like a chess match.

Players have same weapons and vehicles. Their uniforms are similar so I included a modified military symbols feature to help players (This option can be disable) to recognize ally units and vehicles. All vehicles will be shown on RADAR as red icons on both sides so no one has advantage as I pick the right sides and vehicles on purpose. Finally players have the same number and types of ally groups to help them to create different tactics.
